推荐答案
我在Ruby Mine中运行时遇到类似的问题:
I had a similar problem running from Ruby Mine:
您是否在以下位置设置了Oracle clinet路径:
Do you have the Oracle clinet path set in:
DYLD_LIBRARY_PATH
我在终端中设置了它们，但是我必须确保RubyMine在运行配置文件中设置了环境变量:
I had them set in my terminal, but I had to make sure that RubyMine set the environment variables in my run profile:
DYLD_LIBRARY_PATH=/usr/local/oracle/instantclient10_2
NLS_LANG=AMERICAN_AMERICA.UTF8
运行脚本可能无法在与终端相同的位置查找环境变量.
Running scripts may not look for environment variables in the same place as terminal.
您可能必须按以下方式运行rails脚本:
You may have to run the rails script as:
env DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH NLS_LANG=$NLS_LANG rails g scaffold ...
